Answer:

$\large \boxed{\mathrm{view \ explanation}}$

Step-by-step explanation:

-45x + 40

Factor out 5 from the expression.

5(-9x) + 5(8)

Take 5 as a common factor.

4w + 9( -6 - 3w)

Expand brackets.

4w + 9(-6) + 9(-3w)

4w - 54 - 27w

Combine like terms.

4w - 27w - 54

For what value of y does 125=(1/25)^y-1

Alex777 [14]

Answer:y=-1/2

Step-by-step explanation:

125=(1/25)^(y-1)

5^3=(5^(-2))^(y-1)

5^3=5^(-2(y-1))

The same base eliminate each other we then have

3=-2(y-1)

3=-2y+2

Collect like terms

2y=2-3

2y=-1

Divide both sides by 2

2y/2=-1/2

y=-1/2
